A modern, lightweight diagram editor with a built-in AI co-pilot. Describe your diagram in plain language and watch it appear — or build it node by node with precision tools.
Powered by Google Gemini — describe your diagram in plain language, attach a screenshot, or upload source code. The AI builds your flowchart live, node by node, connection by connection.
AI features require a Google Gemini API key — the core editor works without one. How to get one →
